Hybrid Approach for Face Recognition from a Single Sample per Person by Combining VLC and GOM

open access: yesJournal of Intelligent Systems, 2019
This paper proposes a new face recognition system based on combining two feature extraction techniques: the Vander Lugt correlator (VLC) and Gabor ordinal measures (GOM). The proposed system relies on the execution speed of VLC and the robustness of GOM.
